Restart your device when you are facing Wi-Fi issues. This is the first step you should take. This is a simple diagnosis that you can perform if you are technologically inclined.

Press and hold the power button for a few seconds to power on or turn off your device.

 

Restart the Modem and router

If the previous solution did not work then you need to restart your modem or router. The problem should be eradicated once you perform this step.

  1. Press the power button on your modem or router
  2. Unplug your router or modem from its power outlet
  3. Wait 15-20 seconds, then plug it back in
  4. Allow the device a minute or two to turn back on

Another solution is to forget the network. Once this is done you can try to add the network again.

There could be an issue with your network and changing the DNS settings could help with restoring the Wi-Fi connection.

  9. Switch its status from DHCP to Static
  10. Scroll down towards the fields labeled as DNS 1 and DNS
  11. Type in your desired DNS addresses
  12. Hit the Join button when you’re done

 

Perform a factory data reset

If the previous solutions don’t work then you need to do a factory reset. This should be your last resort. Ensure that you back up important data because they can be lost after a factory data reset.

  1. Turn off your device
  2. Press and hold “Volume Down” and “Power“.
  3. Keep holding the buttons until you see the Recovery screen.

  2. Ok so its only my s8 that is saying that wifi is unavailable. Every other device in the household is completely fine. I’ve tried all the solutions and nothing is helping. What do I do as I am getting frustrated.

  4. I have 2 phones right now connected to different providers. One is the worst phone ever made (not exaggerating) and the other is the Galaxy S8. The worst phone ever produced gets a great WiFi connection in my garage and my S8 barely gets a connection and if it does, it drops it shortly after. This is extremely frustrating. This has been going on for over a year so updates and all of the other things aren’t the solution.

  5. i’ve master reset my samsung s8 plus, clear the cache & rebooted and also restart the wifi router & forgot it then added again but still it’s not working. it connect & disconnects again and again within seconds

  13. Bonjour, je suis Monsieur Shaby de la République Démocratique du Congo.
    J’ai un problème avec mon Samsung galaxy s8+, le wifi ne s’active pas. j’ai éteint et rallumer, j’ai réinitialiser mais le problème persiste toujours. que faire

  14. Hallo, trotz zurücksetzen auf Werkseinstellungen. Erkennt mein S8 zwar das WLAN, verbindet sich auch, aber es zeigt keine Webseiten. Alle anderen mobilen Endgeräte haben diese Problem nicht.

  15. I chose PEAP mode.
    The certificate doesn’t appear. So I can’t select it
    When I selected “Don’t validate” option
    I got the notification “No certificate specified. Your connection won’t be private”

  16. I have tried everything you listed and nothing has changed, I have also checked if the issue is solved on safe mode and it isn’t.

    My phone stopped getting internet when connected to my home range extender (“Internet may not be available” message) but still works when connecting it to the main router. I can connect every other device to the range extender (I am guessing it is not the range extender’s problem then).

    Please help!

  17. My S8 still will not connect to my home wi fi, I have tried all the tips on here, I have tried the usual turn of the phone and then back on again, soft reset all to no avail.

  19. I too have been having wifi connectivity issues, I’ve had the modem router checked out the radio program app I listen to add night check their app and now I see this has been a recurring problem for many
    I have shut off phone and modem did the factory reset and still have issues even after the last update a few days ago. Need this fixed.

  20. After the update on 26/Aug/2019, I started facing the issue that the wifi disconnects when trying to download something. I am using Galaxy S8+ handset. Clearly, this happens only when try download android update, or anything from playstore. The wifi works smooth in all other cases, like browser search and whatts app videos. The same issue is seen there with one more Galaxy S8+ in my home.

  21. Hi, I am having issues with wifi connectivity/range on my S8. when I am sitting near to the router it works fine but when I go to another room or at some distance from wifi router it starts showing limited access and then it starts connect/disconnect process. Need some help

  22. Hi Iive been using my Samsung Galaxy S8 to watch movies using Hulu, Netflix, and other “Firelinked” sites that I’ve downloaded. Up until now everything was fine when utilizing this feature, except for the “buffering” that may happen once in a while but that’s just goes with the territory with this. Today I watched a movie with my wife without incident, however when we decided to watch another, that’s when one very bothersome issue occurred.. The issue being the movie would stop playing every 3 – 5 minutes regardless of the site I was on or when we decided to try another movie figuring this was just an isolated issue with the movie itself. I tried everything from re-booting phone & modem to clearing out old unused apps to cleaning out out catches for the apps. Nothing has resolved my problem, whether I use another site or go to another movie, the movie will stop every 3 – 5 mins throughout . I could really use any suggestions out there, so far I haven’t been able to find anything similar online to compare to. Thank you ahead of time. Sincerely, Damian J Zajac

  23. I have done all the solutions you suggested. I even did a factory reset and still my wifi wont stay connected to my Samsung Galaxy s8. Anything else I can do. It has updated twice and that didn’t help.

  26. I am having exact same problems as everyone else, will not connect to my WiFi & none of your suggestions work – this started w/update of 5/7/19. All my other devices will connect/are connected. HELP for Pete’s sake

  27. Has anyone figured what to do? I have done everything written above and nothing works kn my wifi. This happen when my phone died. Daym. Updating the system def feffed this up

  28. I swear to god Apple is paying Samsung or something

  35. We connected to wifi in a pub, the phone froze and then would not connect to any other wifi network. We have tried a full factory reset and the wifi will not turn on, it just turns itself off again. We’ve tried all that you have suggested before a factory reset and nothing has helped.

  36. hi Thanks for the support. my problem is bit different. my wifi turns on and off automatically every 10 seconds. it will be on 10 seconds and will start search for available wifi but turns off for 3 seconds. it started yesterday and drains the battery quickly as well. please help me to resolve this issue

  38. I have a Samsung S8+ that I purchased new a out 6 months ago. Since my purchase I have received several software updates. It seems that after each update my ability to pick up wifi has gotten worse. I can be standing next to 3 people with much cheaper phones, and they are able pick up public wifi that do not even show up on my phone. For example I know people who sit in Walmart Parking Lot and use Walmarts Wifi. I Lose wifi signal al as soo. As I walk out the doors.

  39. Hello. I tried all of this with my samsung galaxy s8+ but no one work. When i connect to my wifi network i got connection for some minutes and then i lost the internet connection but the sign of wifi still shows me like there is an internet connection on my phone. But in reality i do not have an internet connection and all other phones connected to the same wifi either lost the connection untill i turn off wifi on my phone, all of them get the connection back. I tried this on many other wifi and the same problem happens. Please help me what to do

  40. I tried every troubleshooting you have provided but it doesnt work on my handset, last thing i did before it grays out the wifi i deleted my google play account and created a new one then delete and create probably i did it 4-5 times just to have a new account for mobile legends then it disconnects me to wifi, factory reset didnt work. I visited the service center and they wanted to change the mother board which i dont find it reasonable to pay for an expensive phone like s8 that i am expecting to last without any issues, please help thank you

  41. Hi i have an s8 it connects to my home wifi and has also connected to other home wifis ,the problem I am having it will not connect to any secondary devices like alexa speaker or my drone, it finds the wifi they put out but not connecting to it , have update my phone and still nothing any help plz.
    thanks adrian

    1. Hey! I had a lot of issues with my Samsung galaxy s8+ lately due to this authentication error. I got the phone a few months ago and it was working fine until this week. Resetting the router didn’t help (I have an Ubee), neither did flight mode, restarting the phone, forgetting the network or anything else. Last thing I tried was to manually input the mac address of my phone on the modem/router configuration page and save it for both 2G and 5G networks. It’s been working ever since, so I suggest you try that at least. Otherwise, the best solution so far is to contact your net provider and request to change your router/modem, as this has worked for others.

  42. I am having the same issue, my brother has the same phone but wifi stays connected all the time. I took it to vodafone who then sent it to their repair centre, came back the issue remains. I spoke to a staff in vodafone who said they dont really change the wifi card or anything. They just make sure it turns on and charges etcc and then send it back.

  43. I have tried every solution to fix my galaxy s8, nothing has worked. When will Samsung recognize this problem and fix it.

  44. Im using samsung s8 plus.working in dubai uae.my phone has some issues in wifi connection before but it was manageable. But when i click on the update on March 22,2018 and go thru the update from the wifi from my work, problem came which when i reach my accomodation i cannot connect to the wifi even how many times i tried. I do what the guide says but still cannot connect.other mobile was working well with the same wifi. Kindly help coz im thinking now its a bad idea im following samsung models as a choice when im buying.i buy my phone when it lunch last year.im your fan..kindly dont disappoint me..waiting for your reply..

  45. Disabling IPv6 feature on your router will fix this issue. Also you can set up your phone to use static IP address. Then reset your network settings on your phone and connect to WiFi again.

    At least this fixed my WiFi issues on Galaxy S8+. Also fixed issue on Huawei P9.

  46. I was having the same issue, my Samsung Galaxy Note 8 phone was refusing to stay connected to my home Wifi. I got an excellent service tech at Verizon just now who solved the problem quickly. Here’s what worked:
    Go to Settings
    Click on “General Management”
    Click on “Reset”
    Click on “Reset Network Settings”
    Click “Reset Settings”
    Click “Reset”
    Click “Reset” again

    Then log back into your wifi network. So far it hasn’t dropped again, so that seems to have fixed whatever was going on.

    1. Thanks so much Susan. I have been pulling my hair out and I have through forums upon forums. Your fix worked perfect !!! Thank you so much for taking the time to post.

      I’m finely sane again 🙂

    2. Susan, thank you, thank you, thank you! This has worked! I had tried multiple help sites, technical support staff in online chats and phone, and your solution worked!! Samsung should include this in every phone they sell, because it seems like lots of people have the same problem! Again, thank you!

  47. How would you turn on smart switch and what connection does WiFi have with smart switch seriously, people says anything

  48. I have a Samsung s8, as long as I have the location icon turned on my wifi works great. With in minutes of turning the location off I loose my wifi. Any ideas thanks.

  49. I’ve had my S8 since Black Friday and it worked fine at first. Two days after getting the phone I notice my phone was connected to WiFi however there was a little exclamation point and when I checked the status it stated “internet may not be available”. I turned my wifi off and on and it went away. Then two minutes later it popped back up. I did some research and tried all the tricks stated above and read other blogs. I called Samsung and they stated they weren’t aware of this issue and to try a factory reset…. So I did. And guess what… It STILL DOESN’T STAY CONNECTED. I contacted Samsung again and the only solution they had was for me to mail them my phone which is not an option for me since it’s my only phone and I have a small child at home. I’m beyond frustrated with Samsung and my device!

    1. Hi Teddi,

      Any updates on this issue?

      I am also facing similar problems with my wifi connection. Also the message: “internet may be not available” sounds very familiar to me.

      It looks like this is an global issue on the s8 phones (i am living in the Netherlands)

      Best regards,
      Marc

      1. Did u get a fix for this? I connect to the wifi also but my S8 says “internet not available” when I try to connect to any american airport wifi ( while my I phone connects effortlessly 😡)
        Help!

    2. Omg me too! Ive got same problems
      with my wifi connection. Same message: “internet may be not available” And it’s annoying cause it’s using up my monthly data while it should be on wi-fi cause I’m at home!

      Help! I’m loving this phone but not now with this issue!

      1. google it..
        then so this corny joke works… literally just use Googles Servers. **for novies the 4 octets in quotes are the exact numbers to type into DNS
        DNS#1
        8.8.8.8
        DNS#2
        8.8.4.4

        the “Internet may not be available” exclamation! point meaning “Connected but fucked up.” usually means your router is having some weird issue meaning;

        – if your wifi is set up with a specific password protocol and you pick the wrong one… You will get that.
        – If your router isn’t handing out DHCP ip addresses.
        – I’m it, i can walk anyone through it but i could go through this list from memory for hours. do yourself a favor… find an old KNOWN WORKING device. After testing making sure it connects… write down everything you see under “NETWORK PROPERTIES” or whatever… then FORGET the network in the old device..
        2: now re-program it in again… are you connected with the old device?
        if YES then its a Samsung setting…
        if NO … i think you guys see where this is going…..
        WPA 1 and 2 Personal are the safest. i’d tell ya’ll to use WPA2 Enterprise but if your at this sight that might be to heavy right now. If your router is over 5 or 6 years old… either update it. or throw it away. I’m in IT i always tell ppl… is 25$ worth all the bullshit you’ve had to go thru looking back? If you could pay 25-50$ and breeze past these problems instantly … would you pay it? or would you keep banging your head against a wall?

        If your answer is “Hell yes i’d pay…” then toss your old shit actually fuck that, turn it into a secondary access point and FLASH it with DD-WRT :X … yah i know thats a bit much for this forum but if your extremely unfamiliar… ifind a 13 year old gamer kid, he’ll have it done in 5 minutes with 5 minutes to spare.

  50. I got my S8 phone 5 days ago because my LG G3 crashed (after working perfectly for 3 years).
    From the first moment my S8 had problems connecting to my home WiFi. I googled and apparently this a common issue!
    I tried different tricks including the ones in this page. All the solution were temporary and after e short while it kept going back to “failed to obtain IP address” or “internet may not be avaiable”. Really frustrating when you pay a lot for a new phone which is supposed to be the best phone in the market!
    Anyways, I tried this trick and it seems to work perfectly for me since 2 days ago:
    I connected to 5GHz frequency thing of the router (apparently it can be 2.5 or 5GHz….I’m not an expert! 🙂 ). It works perfect and fast with no interruptions.
    If you don’t have a super big house and you are not that far from modem/router there is gonna be no problem with 5GHz.
    Give this one a try and good luck!

  51. The same is happening to me. This S8 my new phone is not connecting well or consistently to my Wi-Fi extender (low bars inconsistent connection) although my old S4 works seamlessly with it.
    I’m frustrated and seeking solutions?

  52. hi I just plugged my TPL 300mbps range extender and notice that on my samsung s8+ signal is unstabile? While on Iphone 6s, laptop it is not it is working well with extender.

    1. The same is happening to me. This S8 my new phone is not connecting well or consistently to my Wi-Fi extender (low bars inconsistent connection) although my old S4 works seamlessly with it.
      I’m frustrated and seeking solutions?

  53. My phone says i must update a wireless WI-FI,which i did and after tha it says download i pressed it and that download it restarted now it says no command,it switches itself on and off

  54. I have tried to reload my phone and i read all your instructions but my phone is still de same pleas help,now it says no command

  55. My Samsung S8 has intermittent data connection while maintaining a strong local WiFi connection, for apps like Viber, and Fiverr. For Gmail it only refreshes the data or sends emails from the outbox if I specifically refresh it.

  56. My wifi connects and disconnects on its own. It literally goes on and off like blinking lights. Tried these and still have the same problem. Anyone else have this issue?

  57. Not only is my phone unreliable on the Wi-Fi but it is also unreliable on the Bluetooth like when trying to transfer movies from my Hopper 3. I am disappointed.

  58. Tried suggested solution no help. Still having problem with WiFi. Does not stay on!!!
    Please send a fixable solution. £700 and not happy!!!

  59. I have S8+ have tried all of the solutions and nothing is working. My carrier sending me a new phone that let’s hope has sodtware fix for this widespread Samsung 8 issue

  60. I can’t seem to download apps without wifi and I don’t have good wifi in my area. Is there a solution to this or did Android actually make a phone without the ability to download apps without wifi?

  61. Hello, I was having the same wireless problem of dropping the signal while at home. Come to find out, my SMART NETWORK SWITCH was OFF. I turned it ON and my signal dropping quit completely. I hope this helps someone else

    1. Hey Max thanks for this, in my s8 plus it shows that the switch can only be turned on if the mobile data is turned on. Any suggestions?

    2. I have the Galaxy S8 but for the life of me, can not find the “Smart Network Switch”. I went to Settings – Connections – Turned my Wi-Fi ON (as I have been leaving it off, since it only works using data) Then clicked on the 3 dots at top – Advanced. But, there is no SMART NETWORK SWITCH. I have a switch to mobile data, turn on Wi-Fi automatically, Wi-Fi power saving. Then it says NETWORK SETTINGS, under that is Wi-Fi notifications, show Wi-Fi pop up, Manage networks, Wi-Fi control history. That’s it.

  62. None of these worked for me..it connects to my WiFi then two seconds later it says ” WiFi disconnected” and every time I get a notification through snap chat or an app, it automatically pulls my home screen up and won’t shut off??

  63. Both our S8+’s have the same problem. We connect to our local cable provider’s public wifi (Cablevision / Optimum). It requires you to log in, and then you select ‘auto’, select your phone time, and enter a ‘name’ for your phone. You submit, and you are connected. Later that day you find yourself back in the area of your provider’s web site, and you should be automatically logged in – but you are not; it doesn’t remember who you are. This is very frustrating! Thanks!

  64. It seems my phone will connect to 5gz internet but not 2.4 gz. I had my internet replace my router and I can now connect to 5gz internet. I still can’t connect to 2.4

  65. This is a really dumb question, but I’m not really sure. When completing a factory reset, what all is considered the data that may be lost? Does it include apps? Does it include data that might be entered into apps? (I use an app to track gas mileage. Every time I get gas I enter it into the app.) How bout photos and videos? Thanks for your help!

    1. No, it is not a dumb question 🙂 Well, factory reset wipes everything you have on your device. So, before you start with the factory reset, you should back up everything you have on your phone. It means that you can backup your files, apps, and everything else you keep on your device. If you are not sure how to do that, follow the steps in this article: https://www.technobezz.com/how-to-back-up-android/

  66. Just got the phones today, all 4 phones refuse to connect to wifi. I’m returning for something better phones . I don’t have time to do Samsung trouble shooting wrk. ‘m done, never again.

  67. Salem problem here, my S8+ connects just fine and after some time has connection issues until I turn off WiFi and set again

    1. Luis,
      I got my S8+ on June 2 with your same problem and I follow or the tips here but the problem still the same. Where you able to solved it? Thanks!

  68. Its my s8 + wifi connectivity it connects and disconnects again after sometime i tried using my galaxy s5 and it works fine…. so the real problem is s8 wifi connectivity please help

  69. I’ve had to reset my network settings once already. It worked. But that was on Saturday it’s now Tuesday and it seems I need to do it again. Come on Samsung get it together! There’s a lot I love about this new S8+ but this is a very annoying problem as it resets a bunch of settings on your phone. They say there is an update hitting Korea but how about Canada. PIA
